  • the term "sector" may be used herein to refer a cell, or a section of a cell, serviced by an AP.
  • an access network controller may refer to the portion of a communication system configured to interface with a core network (e.g., a packet data network) and route data packets between access terminals (ATs) and the core network, perform various radio access and link maintenance functions (such as soft handoff), control radio transmitters and receivers, and so on.
  • a core network e.g., a packet data network
  • ATs access terminals
  • An ANC may include and/or implement the functions of a base station controller (BSC), such as found in a 2 nd , 3 rd , or 4 th generation wireless network.
  • BSC base station controller
  • An ANC and one or more APs may constitute part of an access network (AN).
  • An access terminal (AT) described herein may refer to various types of devices, including (but not limited to) a wireless phone, a cellular phone, a laptop computer, a multimedia wireless device, a wireless communication personal computer (PC) card, a personal digital assistant (PDA), an external or internal modem, etc.
  • An AT may be any data device that communicates through a wireless channel and/or through a wired channel (e.g., by way of fiber optic or coaxial cables).
  • An AT may have various names, such as access unit, access node, subscriber unit, mobile station, mobile device, mobile unit, mobile phone, mobile, remote station, remote terminal, remote unit, user device, user equipment, handheld device, etc. Different ATs may be incorporated into a system.
  • ATs may be mobile or stationary, and may be dispersed throughout a communication system.
  • An AT may communicate with one or more APs on a forward link and/or a reverse link at a given moment.

  • FIG. 1 illustrates a wireless communication system 100 configured to support a number of users, in which various disclosed embodiments and aspects may be implemented, as further described below.
  • system 100 provides communication for a number of cells 102, including cells 102a-102g, with each cell being serviced by a corresponding AP 104 (such as APs 104a-104g). Each cell may be further divided into one or more sectors.
  • Various ATs 106 including ATs 106a-106k, are dispersed throughout the system. Each AT 106 may communicate with one or more APs 104 on a forward link and/or a reverse link at a given moment, depending upon whether the AT is active and whether it is in soft handoff, for example.
  • a solid line with an arrow may indicate information (e.g., data) transmission from an AP to an AT.
  • a broken line with an arrow may indicate that the AT is receiving the pilot and other signaling/reference signals (but not data transmission) from the AP.
  • the reverse link communication is not explicitly shown in FIG. 1 .
  • System 100 may be configured to support one or more standards, e.g., IS-95, cdma2000, IS-856, W-CDMA, TD-SCDMA, other standards, or a combination thereof.
  • system 100 may be a high rate packet data (HRPD) system, such as specified in " cdma2000 High Rate Packet Data Air Interface Specification," 3GPP2 C.S0024-A, Version 2, August 2005 (also referred to as “1xEV-DO").
  • HRPD high rate packet data
  • an AT intentionally abandons a connection in one communication system (e.g., an HRPD system) due to receiving a page message from another communication system (e.g., a "CDMA2000 1x" type system, such as specified in " Physical Layer Standard for cdma2000 Spectrum Systems," 3GPP2 C.S0002-D, Version 2.0, September 2005 ).
  • the AT may receive the page message either by tuning away to the other system periodically or through the HRPD system as a tunneled message.
  • the HRPD connection is intentionally abandoned (or dropped) by the AT, as opposed to resulting from any unintended failure in the network infrastructure or deployment. Therefore, such a connection failure may not be counted in compiling the connection failure statistics (e.g., for purposes of identifying the problematic spots in the system, etc.).
  • an AT may be the entity being able to determine readily and with certainty which connection failures are intentional (e.g., as a result of tuning away to another system) and which ones are unintentional.
  • Embodiments disclosed herein relate to methods and systems for reporting and compiling connection failures in wireless communication systems.
  • the AT when an AT experiences a connection failure (e.g., an unintended connection failure), the AT may generate a "connection failure record" associated with the event, and send a message containing the connection failure record (or "connection failure report message") to an AN with which it has since established the connection.
  • a connection failure e.g., an unintended connection failure
  • the connection failure record may include (but not limited to): a time stamp associated with the time when the AT detected the connection failure; the sector identification (ID) associated with the reference pilot in the AT's active set when the connection failure occurred; the location information (e.g., the longitude and/or latitude) associated with the sector at which the connection failure occurred (such may help, for example, the network operator to determine the coverage holes), etc.
  • the connection failure record may also include a reason (e.g., a "reason code") for the connection failure.
  • the reason code may take values indicated as follows: Reason Code Category 0X0 General connection failure (excluding failure due to tuning away to another air interface) 0x1 Connection failure due to tuning away to another air interface 0x2 Connection failure due to position determination tuning away
  • the reason code in the first row represents a category of connection failures (e.g., unintended ones) which may be indicative of the health of the system.
  • the reason codes in the next two rows represent two categories of connection failures which may also be useful for the network operator to keep track of ATs' activities, for example.
  • the inclusion of a reason code in a connection failure record may allow the AN to determine which connection failures are unintended.
  • the AN may send a "connection failure report acknowledgement (ACK) message" to the AT, upon reception of the AT's connection failure report message.
  • ACK connection failure report acknowledgement
  • the AN may for example use the information from the connection failure report message (or forward such information to another AN as further described below) for purposes of compiling the connection failure statistics (e.g., the number of connection failures and associated time occurrences and locations, etc.), so as to identify problematic spots in the system and improve the quality of service.
  • the AT may purge the connection failure record(s) included in a connection failure report message, upon establishing the connection with and receives a connection failure report ACK message with the matching ID from the AN.
  • the AT may store the corresponding connection failure records (e.g., in a memory), and report such later when the AT establishes the connection with an AN.
  • the AT may be allowed to store up a predetermined number of connection failure records, for example.
  • the AT may also repeat the connection attempts according to a predetermined scheme (e.g., waiting for a certain period of time between two successive connection-attempts as further described below). Such may help conserve the AT's battery power.
  • the AT may await T seconds and then perform the following:
  • FIGs. 2A-2B illustrates an embodiment 200 of connection failure reporting in a communication system.
  • an AT 230 may initially be in communication with a first AN 210.
  • AT 230 may then move into an area 240 with no coverage, hence, causing it to lose the connection with first AN 210.
  • AT 230 may establish the connection with a second AN 220.
  • AT 230 may send a connection failure report message associated with the connection failure it has experienced to second AN 220.
  • Second AN 220 may in turn forward the connection failure information associated with AT 230 to the AN identified by the sector ID included in the connection failure report message (e.g., first AN 210 in this example), so as to help the first AN to compile the connection failure statistics and so on (such as described above).
  • the connection failure report message e.g., first AN 210 in this example
  • FIG. 3 illustrates a flowchart of a process 300, which may be used in an embodiment to implement connection failure reporting and compiling in a wireless communication system.
